With regards the the watercooling blocks I went with the EK FC blocks, I wasn't sure about them like most people but when you get to feel them they are quality parts, plus I think they look good with the full cover backplates. Anyway here is my spec,

Ran some benches including Prime for 12 hours and a looped 3dmark 11 for GPU / CPU stressing for an hour and max temps were CPU 53C / GPU 51C.

If you are looking at a similar build I would say that the 600t is not the greatest case for watercooling case, you are quite limited in the rads you can use, but you can still get some good results if you try. If you are wondering where the SSDs are I put a pair of them in a Silverstone drive bay converter which can house a 3.5" or a couple of 2.5" SSDs.

I'm liking the build, nice and clean. First time seeing those new EK blocks in action - alot of people don't care for them on account of the circles and the previous corrosion that people were experiencing with EK blocks - I think they look alright. Some white or blue led strips would look pretty cool in there if you are the type who cares about that stuff.
